Description

A lifting device for butterfly valve butterfly plate

Technical Field

This novel lifting device who belongs to lifting device, concretely relates to lifting device for butterfly valve butterfly plate.

Background

The butterfly valve is a valve commonly used in various industries and has the advantages of simple structure, small installation size, quick opening and closing and the like. The butterfly valve mainly comprises three major components, namely a valve body, a valve rod and a butterfly plate, wherein the butterfly plate is a sealing element of the butterfly valve, the butterfly plate is generally of a disc structure, coaxial shaft holes are machined in two sides of the butterfly plate, the butterfly plate is fixed on the valve body through the valve rod, and the butterfly plate moves around the valve shaft to realize the opening and closing of the valve. Because the butterfly plate is a disc-type part, a hoisting hole is not additionally processed for the sealing element generally, and the butterfly plate is hoisted in a mode of sleeving the shaft hole by the rope.

Along with the wide application of butterfly valve, the aperture specification of butterfly valve is bigger and bigger, in many application occasions, the bore of butterfly valve has exceeded DN2000, the weight of single butterfly plate exceeds 2 tons, there is very big potential safety hazard in direct rope cover shaft hole hoist and mount, lift by crane the easy slippage of in-process, the shaft hole terminal surface is sharp easily to the rope production cutting, destroy the security of rope, the rope is lifting by crane the easy lacquer painting that destroys the shaft hole terminal surface of in-process friction back and forth simultaneously, influence the appearance quality of final products. A suitable hoisting tool is urgently needed to solve the hoisting problem of the large butterfly plate.

SUMMERY OF THE UTILITY MODEL

This novel defect to prior art provides a lifting device for butterfly valve butterfly plate.

This is novel to realize like this: a lifting device for butterfly valves and butterfly plates comprises a lifting frame, bolts and lifting bolts.

According to the hoisting tool for the butterfly plate of the butterfly valve, the hoisting frame is installed in the shaft hole of the butterfly plate through the bolt, and the lifting bolt is installed on the end face of the outer side of the hoisting frame.

According to the lifting tool for the butterfly plate of the butterfly valve, the lifting frame is designed in an integrated mode, and the upper surface of the lifting frame is provided with the two screw holes for being fixedly connected with the butterfly plate.

According to the hoisting tool for the butterfly plate of the butterfly valve, arc surfaces are designed on two sides of the top of the hoisting frame and are matched with the inner surface of the shaft hole of the butterfly plate.

According to the hoisting tool for the butterfly valve butterfly plate, the outer end face is provided with the screw hole for installing the lifting bolt.

A lifting device for butterfly valve butterfly plate as above, wherein, the lifting eye screw matches the rope and hoists.

The hoisting tool for the butterfly plates of the butterfly valve is characterized in that two groups of hoisting tools are used for each butterfly plate and are respectively installed in the shaft holes on two sides of the butterfly plate.

This neotype effect that is showing is: the hoisting of large-scale butterfly plate can be realized to can not harm butterfly plate shaft hole terminal surface paint, convenient to use, safe and reliable. The main body of the hoisting tool is a hoisting frame, the structure is simple, the installation is convenient, the hoisting tool can be conveniently installed in the shaft hole of the butterfly plate, and the butterfly plate is reliably connected with the hoisting tool through bolts. The end of the hoisting frame is provided with a screw hole, so that a lifting bolt can be conveniently installed and hoisted through a rope. The butterfly plate is hoisted by installing the hoisting frame, so that the butterfly plate is safe and reliable.

Drawings

Fig. 1 is a lifting tool for butterfly plates of butterfly valves provided by the invention;

in the figure, 1 a hoisting frame; 2, bolts; 3 lifting eye screw.

Detailed Description

The invention is described in detail below with reference to the attached drawing figures:

as shown in fig. 1, a lifting tool for butterfly valve butterfly plate comprises: hoisting frame 1, bolt 2, eyebolt 3. The hoisting tool is mainly used for hoisting butterfly plates of butterfly valves, in particular large butterfly plates. The hoisting frame 1 is a metal part, is rectangular as a whole, is provided with an arc at the upper part, can be matched with the inner surface of a shaft hole of the butterfly plate, and increases the contact area; two screw holes are processed on the upper surface of the hoisting frame 1, and the butterfly plate can be fixed through bolts 2; the two screw holes can be fixed at will according to the size of the butterfly plate, but the end part of the hoisting frame 1 is exposed out of the shaft hole of the butterfly plate and has a certain distance; a screw hole is processed on the end surface of the outer side of the hoisting frame 1, and a lifting ring screw 3 can be installed. Thus forming the lifting tool for the butterfly valve and the butterfly plate. And finally, installing a hoisting rope on the lifting bolt 3, and thus, hoisting the butterfly plate.

A hoisting tool for butterfly plates of butterfly valves is characterized in that a hoisting frame is connected with a butterfly plate of a hoisting main body through bolts, and the hoisting tool is safe and reliable; the hoisting frame is also provided with a lifting ring screw, so that the hoisting is very convenient to implement.

The technical characteristics for realizing the invention are as follows:

1. design of integrated hoisting frame

This lifting device ingenious design integral type hoist and mount frame, install in the shaft hole of butterfly plate, avoided hoist and mount rope and butterfly plate direct contact. On the premise of ensuring the reliable and convenient implementation of hoisting, the hidden danger of butterfly plate appearance scratch and damage caused by the implementation of hoisting is avoided.

2. Broad versatility

The lifting tool is mainly used for lifting butterfly plates of not less than DN2000 butterfly valves and can also be used for lifting butterfly plates of other specifications. Two screw holes are designed in the upper portion of the hoisting frame, butterfly plates of different specifications can be matched, each hoisting frame only needs to be fastened with a butterfly plate through a bolt, and the universal hoisting frame has wide universality.

3. Simple structure and convenient installation

Each group of the hoisting tool consists of three parts, namely a hoisting frame, a bolt and a lifting ring screw. The structure is very simple, and during the use, install the butterfly plate to hoisting frame through the bolt on, then install eyebolt and can implement the hoist and mount, simple to operate, safe and reliable.
